摘　　要：煤矿井下液压系统中，液压电磁阀防爆是必须解决的关键问题。本文论述了煤矿井下自动化设备上采用的液压电磁阀的两种防爆方式，即隔爆方式和本质安全方式。Explosion-proof of hydraulic solenoid valves for well hydraulic system is a bottleneck problem to have to be solved. This paper introduces two exposion-proof modes (flame proof and essentialsafe mode)which are used in automation equipment of underwell ofcoal mine.
